[ Allium Central ]  [ Hardy Hibiscus Home ]  [ Cleome Studies ] [ Rock Gardening ]


Welcome to PlantBuzz! is the starting point to Mark McDonough's eclectic horticultural musings and illustrated plant studies on the web.  From here, you can access several areas of horticultural study that monopolized my attention over the past 30 years.  The section for which I have greatest ambition is Allium Central, the goal being the most complete resource on the web dedicated to the genus Allium.  With similar scarcity of on-line information as Allium, the hardy hibiscus are a wonderful group of woody shrubs and herbaceous perennials worthy of greater prominence in gardens and literature.  Visit the Hardy Hibiscus Home to learn more about these late blooming plants, and to access pertinent links.   To round out the miscellany of horticultural topics, Cleome Studies provides links and information on this large genus of showy annual plants, for which only a few species are known and grown.  And last, there is the Rock Gardening page, a miscellany unto itself, exploring any and all alpine, rock garden, and woodland plants that interest me.
